*Hive Mind*, by Garett Jones

I am very excited to report that next week will see the publication of Hive Mind: How Your Nation’s IQ Matters So Much More Than Your Own, by my colleague Garrett Jones, with Stanford University Press.  This will go down as one of the social science books of the year.

Here is Garett’s opening paragraph:

This isn’t a book about how to raise IQ: it’s a book about the benefits of raising IQ. And a higher IQ helps in ways you might not have realized: on average, people who do better on standardized tests are more patient, are more cooperative, and have better memories. But while dozens of studies by psychologists and economists have established these links, few researchers have connected the dots to ask what this means for entire nations. And since average test scores vary across nations—whether we’re talking about math tests, literacy tests, or IQ tests—an overall rise in national test scores likely means a rise in the number of more patient, more cooperative, and better-informed citizens. This in turn means that higher national test scores will probably matter in ways too big to ignore. And if education researchers and public health officials can find reliable ways to raise national test scores, productivity and prosperity will rise where poverty and disease now flourish.

Here is chapter one, here are Garett’s chapter summaries.  Here is Garett’s home page.  On Twitter, here you will find The Wisdom of Garett Jones.

Garett Jones on The Hive Mind

A recent line of research demonstrates that cognitive skills—IQ scores, math skills, and the like—have only a modest influence on individual wages, but are strongly correlated with national outcomes. Is this largely due to human capital spillovers? This paper argues that the answer is yes. It presents four different channels through which intelligence may matter more for nations than for individuals: 1. Intelligence is associated with patience and hence higher savings rates; 2. Intelligence causes cooperation; 3. Higher group intelligence opens the door to using fragile, high-value production technologies, and 4. Intelligence is associated with supporting market-oriented policies. Abundant evidence from across the ADB region demonstrating that environmental improvements can raise cognitive skills is reviewed.

Mindles Dreck is the Dreck of my dreams

I’d like to reproduce chunks of his old yet prescient post (or go here and scroll down to 22 January):

Pundits continue to link the Enron debacle to a need for increased regulation,
especially of derivatives. What most of these people…don’t appreciate is that regulation and/or accounting rules are the
most fertile breeding ground for derivatives and synthetic or packaged
securities. Regulations and accounting rule-inspired transactions
describe the bulk of the well known derivative-related blow-ups of the
last two decades. Proscriptive regulation and the derivative trade have
a symbiotic relationship.

Investors and operating companies buy derivatives for two basic
purposes: speculation and risk transfer. A derivative, (a financial
contract based on the price of another commodity, security, contract or
index) either eliminates an exposure, creates an exposure, or
substitutes exposures. That last one, substituting exposures, is
important to heavily regulated investors.

For example, insurance companies were a goldmine for derivatives
salespeople in the last two decades, only slowing down in the late
1990s. The fundamental reason for this is not because insurance
executives were stupid, but because they manage their investments in a
thicket of proscriptive regulation. Insurance companies have to respond
to their national regulatory organization (the NAIC), their home state
insurance department and the insurance departments of states in which
they sell or write business. They file enormous statutory reports every
quarter using special regulatory pricing, and calculate complex
risk-based capital reports and "IRIS" ratios regularly.

Even though the insurance industry has been heavily regulated
throughout the entire post-war era, the incidents of fraud and
financial mismanagement have been numerous and spectacular.  Remember Marty Frankel?
Mutual Benefit Life? For each of these cases that are in the news,
there are many smaller ones you don’t hear about. Some of that may be
the nature of the industry, but it doesn’t make a prima facie case for more regulation…

Insurance companies often need the yield of less creditworthy
obligations. So derivative salesmen see an opportunity to engineer
around the regulations. They package securities that substitute price
volatility for the proscribed credit risk. Then the investor can be
compensated for taking some additional risk, and the banker can be
compensated for creating the opportunity. A simple example of this is
the Collateralized Bond Obligation (CBO). A CBO is created by buying a
bunch of bonds, usually of lower credit quality, putting them in a
"special purpose vehicle" (SPV) and then issuing two or more debt
instruments from the SPV. The more senior instruments can obtain an
investment grade rating based on the "cushion" created by the junior
debt tranche. The junior bond absorbs, for example, the first 10% of
losses in the entire portfolio and only when losses exceed that amount
will the senior obligations be impaired. The junior instruments, known
as "Z-Tranches" become "toxic waste", suitable only for speculators and
trading desks with strange risks to lay off (or, in a famous 1995 case,
the Orange County California Treasurer).

A CBO is just one example of a credit rating-driven transaction, but most of them achieve the same thing – they decrease frequency of loss but increase the severity.
So they blow up infrequently, but when they do it’s often a big mess.
Ratings-packaged instruments are less risky than the pool of securities
they represent but often riskier and less liquid than the investment
grade securities for which they are being substituted. As a result,
they pay a yield or return premium (even net of high investment banking
fees). That premium may or may not be enough to pay for their risk. But
they pass the all-important credit rating process and are therefore
sometimes the only choice for ratings-restricted portfolios reaching
for yield.

…[Frank] Partnoy is a former derivatives salesperson, and he clearly suggests
that regulation is often the derivative salesman’s best friend.
Complicated rules encourage complex transactions that seek to conceal
or re-shape their true nature. Regulated entities create demand for
complex derivatives that substitute proscribed risks for admitted
risks. If a new risk is identified and prohibited, the market starts
inventing instruments that get around it. There is no end to this
process. Regulators have always had this perversely symbiotic
relationship with Wall Street. And the same can be said for the
ridiculously complicated federal taxation rules and increasingly
byzantine Financial Accounting Standards, both of which have inspired
massive derivative activity as the engineers find their way around the
code maze.

Speaking his mind

Eric Rasmusen (expect controversy from his site) writes:

I would rather see a preacher honestly say, “I believe Christians are better than other people.” A Christian has to believe that. If he doesn’t, he is denying sanctification – he is saying that even genuine Christian belief has no influence on a person’s behavior. Maybe that is true, but should somebody who believes it be a Christian?

The mind of Paul Krugman

Here is an interview with Paul Krugman, talking for the left-wing audience of LiberalOasis and thus, believe it or not, less restrained than usual. Here is one revealing bit, talking about the United States post-9/11: “I felt for a little while there like I was all alone, [that] they’re all mad but me.”

He also uses the phrase “My finest hour” is a non-ironic way, when speaking of the California energy crisis.

He talks about his new book The Great Unraveling: Losing Our Way in the New Century as well. I will offer some comments once my copy arrives.

Garett Jones on open borders

I am very pleased that the new Bryan Caplan and Zach Weinersmith open borders graphic novel has hit #1 on The Washington Post non-fiction bestseller list.  I am also pleased to see Garett Jones examine the idea in a new short paper, here is part of his critique:

I use the same constant returns to scale framework as Caplan, in which the migration of every human being to the United States would increase global output per capita by about 80%. I then estimate that in the benchmark model, where IQ’s social return is much larger than its private return, the per-capita income of current U.S.residents would permanently fall by about 40%. This is not an arithmetic fallacy: this is the average causal effect of Open Borders on the incomes of ex-ante Americans. This income decline occurs because cognitive skills matter mostly through externalities: because your nation’s IQ matters so much more than your own, as I claim in 2015’s Hive Mind. Therefore, a decline in a nation’s set of average cognitive skills will tend to reduce the productivity of the nation’s ex-ante citizens.

I will be sure to link to Bryan’s reply when it comes.

Best non-fiction books of 2015

These are in the order I read them, more or less, not in terms of preference.  And I would say this year had more good entries than ever before.  Here goes, noting that most of the links go to my earlier reviews of them:

First, here are the economics books:

Mastering ‘Metrics: The Path from Cause to Effect, by Joshua D. Angrist and Jörn Steffen-Pischke, technically late 2014 but it was too late to make that list.

Dani Rodrik, Economics Rules.

Richard H. Thaler, Misbehaving: The Making of Behavioral Economics.  Self-recommending.

Garett Jones, The Hive Mind.  Why national IQ matters.

Scott Sumner, The Midas Paradox.  Boo to the gold standard during the Great Depression.

Greg Ip, Foolproof: Why Safety Can be Dangerous, and How Danger Makes Us Safe.

And the rest, more or less the non-economics books:

Robert Tombs, The English and Their History.

R. Taggart Murphy, Japan and the Shackles of the Past.  The last section is brilliant on current Japanese politics.

Michael Meyer, In Manchuria: A Village Called Wasteland and the Transformation of Rural China.  Adam Minter has a very good and useful review of a good book.

Ian Bostridge, Schubert’s Winter Journey.  Will improve your listening.

The Mahabarata, by Carole Satyamurti.  Rewritten and edited to be easier to digest, intelligible and rewarding.  As “an achievement,” this book does have some claim to be number one.

Avivah Gottlieb Zornberg, Bewilderments: Reflections on the Book of Numbers.  You can never read enough commentary on the Torah.

Daniel Tudor and James Pearson, North Korea Confidential, how things really work there (speculative), rain boots for instance are a fashion item and black markets are rife.

Serhii Plokhy, The Gates of Europe: A History of Ukraine, a good general history of the country.

Guantánamo Diary, by Mohamedou Ould Slahi.  He’s a very smart guy.

Ashlee Vance, Elon Musk: Tesla, Space X, and the Quest for a Fantastic Future.

Sebastian Strangio, Hun Sen’s Cambodia.  Goes deep into a place most people are ignoring.

Michael Booth, The Almost Nearly Perfect People.  The Nordics, that is.

Timothy Snyder, Black Earth.  He succeeded in writing an original book about the Holocaust, which is hard to do.

Emmanuel Todd, Who is Charlie?  Background on France being screwed up.

Niall Ferguson, Henry Kissinger, vol. I.  Background on America being screwed up.

Landmarks, Robert Macfarlane.  How to talk, think, and write about the British countryside.

Andrea Wulf, The Invention of Nature: Alexander von Humboldt’s New World.  The best of the various recent books on Humboldt.

Frank McLynn, Genghis Khan.  Background on a whole bunch of other places being screwed up.

Daniel P. Todes, Ivan Pavlov: A Russian Life in Science. I didn’t have time to read all of this book, but it seemed very good in the fifth or so I was able to read.  By the way, the whole salivating dog at the bell story is a fiction.

Pierre Razoux, The Iran-Iraq War, readable and useful.

Charles Moore, Margaret Thatcher: At her Zenith: In London, Washington, and Moscow, vol.2 of the biography, 1984-1987.  This one I haven’t finished yet.  I ordered my copy advance from UK Amazon, it doesn’t come out in the U.S. until early January.  There is some chance this is the very best book of the year.

I don’t quite see a clear first prize.  If I had to pick, I would opt for a joint prize to the biographies of Musk, Kissinger, Thatcher, and Genghis Khan.  This was the year of the biography.

Sorry if I forgot yours, this list is imperfect in various ways!  And the year isn’t over yet, so I’ll post an update on the very good books I read between now and the end of the year, probably on December 31.

Rural China worry about the human capital

This is from a recent paper by Stanford’s Scott Rozelle:

We also seek to explain why parents in rural China appear to be engaging in poor parenting practices. The paper brings together quantitative results from a survey of 1,442 caregivers of 18- to 30-month-old children in children in 11 nationally designated poverty counties as well as analysis of interviews with 20 caregivers in 8 rural villages. The results of the quantitative analysis demonstrate that 42 percent of children in the sample are cognitively impaired and 10.2 percent experience delayed motor development [emphasis added by TC]. According to the quantitative data, the poor cognitive development is not due to the fact that parents do not care for their children, as the majority reported that they enjoyed spending time with their child (88.6%). Nor are the delays due to a lack of a sense of parental responsibility, as almost all caregivers responded that they believed it was their responsibility to help their child learn about the world around them (94.6%). Yet poor parenting practices appear to be in part to blame: quantitative analysis shows a significant positive correlation between singing, reading, and playing with a child and their cognitive and psychomotor development. The empirical data shows, however, that 87.4 percent of parents do not read to their children; 62.5 percent do not sing to their children; and 60.8 percent do not play with their children. In the qualitative section of the paper we provide evidence suggesting that the prevalence of poor parenting practices does not stem from inadequate financial resources or parental indifference to the child’s development. Instead, the three main constraints influencing parental behaviors are (a) not knowing that they should be engaging in these parenting behaviors at this stage in the child’s development, (b) not knowing how to properly interact with the child, and (c) not having time to practice such behaviors.

Like all papers, this one is subject to various cavils and caveats, or perhaps the sample is not truly representative.  Still, it is a useful antidote for assuming that factors of IQ and human capital necessarily give China a big growth advantage in the decades to come.  Chinese test scores are good, but rural China does not always meet the Chinese average, and that is where much of the next wave of growth needs to come from.

Of course for more on these issues you need to read Garett Jones’s forthcoming The Hive Mind.

For the pointer I thank Christopher Balding, here is his new post on how stressed are the major Chinese banks?: “Chinese banks are slush funds to direct capital to preferred companies.”

Spoons and the social discount rate

Its hard to imagine spoons will exist in their current form in 30 years. What does this tell us about the social discount rate?

That is from the ModeledBehavior hive mind.

Let’s assume an intertemporal equilibrium.  The rate of return on buying consumer durables ought to equal (risk-adjusted) the rate of return on capital.  Spoon improvement means a lower rate of return on holding spoons, which means a lower return on durables, which in turn means a lower rate of return on capital investment.  For a given set of interest rates, that implies a higher rate of social discount.

That said, I find it easy to imagine spoons will exist in their current form in 30 years.  What if I were wrong?  I would be overestimating the MU of money in future periods and thus saving too much.  I ought to buy more non-spoon items, renting my current spoons, knowing that spoon improvements will glide me into a cushy retirement.

How bad is the new German trade deficit?

That is the topic of my latest Bloomberg column.  The country suddenly faces many problems at once:

…extremely high energy prices, the need to bail out some of its energy firms, the conflict in Ukraine and the resulting promise to boost defense spending, and possible troubles with Italy in the Eurozone over rising borrowing costs. Germany is either going to do very, very poorly, or will muddle through and manage a major turnaround. I would bet on the latter.

And here is another part of the argument:

And then there is what may be Germany’s biggest problem: complacency. In the last 20 years Germany’s primary education system has had a mixed performance, albeit with some improvements, and its infrastructure is no longer perceived as so efficient or high quality. Yet reform was not imperative, partly because things were going OK enough in Germany.

There is a chance that the current crisis will jolt Germany out of its passivity. Throughout history Germany has managed to reverse some very bad situations, as it did after the devastations of the Napoleonic wars and World War II.

Keep in mind that human capital is the most important determinant of national wealth, much more important than the flows reflected in the trade account in any given month or year. If German reforms boost the ability of the country to train students and to put its people to work, the long-run payoffs could be very high.

In general I have found that wealthy societies deal with “one-off” problems somewhat better than most observers expect in advance.  I will be watching closely.
